Abstract

Surfing or sailing board with two elements (1, 2) adapted to form respectively a front part and a rear part of the float by cooperation of complementary groove-and-tongue joint means consisting of an elongated element (4) and a protuberance (5) adapted to be nested therein. The recess is delimited by a U configuration following a continuous line and whose branches (7, 8) are substantially parallel to the axis of the float and are connected to each other (at 9) on the one hand, and to the edges (10, 11) of the float (at 12 and 13) on the other hand.

Description

"Two-part surf or sail type board float.

The present invention relates to a board float such as a surf board or a sail board comprising several parts which can be separated from one another. The invention allows to have such a float separable into two parts, more easily transportable.

It is known from French Patent No. 2,572,703, the national registration number of which is No. 8417157, a versatile windsurf board conferred by various extensions of its rear. The system allows the transformation of a basic "Fun board" for example into any other type of windsurf, thus giving it multiple uses.

The basic windsurf board can receive a rear part, by interlocking, this interlocking being reinforced by male or female inserts. The rear part is immobilized, upstream, by a stop belonging to the base float; the junction being perfect by a seal made of elastic material. The assembly is made inseparable during use by locks.

Furthermore, document EP-A-0 052 783 describes a similar float having two front and rear elements which can be fitted one into the other, longitudinal. The interlocking parts of these elements have an approximately trapezoidal shape. Consequently, means for locking these two assembled parts must be provided, since the slightest longitudinal separation of the two elements would cause their separation. The invention makes it possible in particular, in its simplest embodiment, to obtain a float in two interlocking front and rear elements, having intrinsic assembly stability.

More specifically, the invention relates to a board or surf type float with two elements adapted to respectively form a front part and a rear part of the float by cooperation of complementary means. in an element, called female, by an elongated recess and in an element, said male, by a projecting projection adapted to fit into said recess, characterized in that said recess being delimited by a following U-shaped outline a continuous line comprising two branches substantially parallel to the axis of the float connected to one another, on the one hand, and to the edges of the float, on the other hand.

Advantageously, the stability of the assembly of the two elements is reinforced by a blocking assembly and / or an interlocking locking assembly.

The characteristics and advantages of the invention will become apparent from the description which will follow by way of example, with reference to the appended drawings in which: FIG. 1 is a plan view of a float according to the invention; Figure 2 is a corresponding side elevation view; Figure 3 is a sectional view along the plane III-III of Figure 1; Figure 4 is a perspective diagram of the float removal area.

According to the embodiment chosen and shown, the board float according to the invention consists of two elements 1 and 2 respectively forming front and rear parts, a fixed fin 3 being visible projecting from the underside of the rear part.

In view of their assembly, the two elements are provided with removal means constituted here by a recess 4 formed in the front part 1 and by a projecting projection 5 formed as an extension of the rear part 2 and adapted to fit into said recess .

The recess 4 seen in plan is delimited by a U-shaped layout with two branches 7, 8 extending parallel to the longitudinal axis XX of the board and connected together by a recess bottom 9 of generally semi-circular shape and at the lateral edges 10, 11 of the board by rounded ends 12, 13. As it appears in the sectional view of FIG. 3, the two elements being produced, according to a usual technique in the field, by molding in thermoplastic resin, comprise a rigid skin constituted by a wall hardened in contact with the cavity of molding and ensuring the confinement of an interior volume optionally filled with a lightened filling material, for example by expansion, foam material or the like.

The internal wall 14 of the recess 4 has an angular profile, practically at right angles, and the external wall 15 of the projecting projection 5 has a corresponding shape with a view to its fitting into the recess and its guidance by the latter.

We see indeed, by considering for example the perspective diagram of FIG. 4 that once presented opposite the recess 4, the projection 5 engages very easily therein thanks to the flaring offered by the rounded 12, 13; then once engaged, it is guided therein by sliding between the branches 7 and 8 until it is fully fitted by the stop of its rounded end against the recess bottom 9.

The nesting thus produced provides an excellent assembly of the two elements, assembly whose quality could already ensure satisfactory cohesion of the assembly.

The invention however offers additional means of consolidating this assembly forming a blocking and locking assembly.

For blocking the nesting, it is provided at the top and near the ends of the projection 15 of the recesses 16A, 16B, 16C forming mortises adapted to cooperate respectively with tenons 17A, 17B, 17C formed projecting in the middle of the bottom. on the one hand, and near the ends of the recess, on the other.

These three mortise-tenon systems block the assembly against any risk of relative angular displacement or twisting of the assembly formed by the two elements once assembled. This assembly is finally ensured by an associated set of three locking devices indicated diagrammatically in FIG. 1 at 21 plumb with the center of the bottom of the recess 9, and at 22 and 23 plumb with the rounded entrance recess 12, 13.

Each of these locking devices is mounted in a depression provided for this purpose in the upper wall of the elements straddling the U-shaped border line of the removal area. They each consist of a system of attachment to a rod, cable or strap adapted to be tensioned by a lever, a system of the so-called toggle type for example, allowing easy and quick maneuvers, both when closing for assembly, and when 'at the opening for disassembly of the board. Thanks to their arrangement at the bottom of depressions provided for this purpose in the upper face of the board, any risk of injury to the user is avoided. In addition, a cover can be provided, if desired, to cover each of these depressions. The central device 21 is oriented longitudinally along the axis XX of the board, while the two lateral devices 22, 23 advantageously have an oblique orientation, for example 45 "from the aforementioned axis, which is a safety factor As shown in FIG. 1, the area of removal determined by the recess 4 and the projection 5 extends over the middle region of the assembled board, therefore over the region most stressed from the point of view of the stresses created by the feet of the user and of the distortions liable to result from use in the structure of the board.

The structure according to the invention provides an extremely advantageous consolidation in this respect, thanks to the stiffening reinforcement effect of the structure provided by the profiled walls 14 of the recess 4, on the one hand, and 15 of the projection 5, on the other hand.

In the embodiment considered above, by way of example, the recess 4 was formed in the part before 1; it goes without saying that the reverse arrangement in the rear part 2 would be strictly equivalent. It is also obvious that the profiles 14 and 15 of the recess and projection walls could be reversed, that is to say made (fig. 3) in chevrons with the point directed laterally inwards instead of the 'be outward. It is therefore clear to a person skilled in the art that numerous variant embodiments remain possible without departing from the scope of the invention. It should be noted in particular that in particular to facilitate manufacture, in particular by molding, it may be preferable to adopt in the U-shape of the recess 4 a slight flaring of a few degrees of the two branches 7 and 8, flaring facilitating the demoulding. Advantageously, provision may be made in certain embodiments for the provision of an elastic seal along the edges of all or part of the assembly.

It is also important to note that instead of the angular profile of the complementary side walls 14 and 15, other forms of more or less rounded profiles may be preferred.

The fastening system of the locking devices can in turn make a fastening with locking by means, for example, of pins or the like.
